fix(plugin-dev): add missing .claude-plugin/plugin.json manifest

The plugin-dev plugin is listed in .claude-plugin/marketplace.json but was the
only plugin in the plugins/ directory without a .claude-plugin/plugin.json
manifest, which is required for installation from the marketplace.

Adds the manifest with name, version, description, and author matching the
marketplace.json entry, consistent with all other plugins in this repo.

 # Changelog
 
+## 2.1.105
+
+- Added `path` parameter to the `EnterWorktree` tool to switch into an existing worktree of the current repository
+- Added PreCompact hook support: hooks can now block compaction by exiting with code 2 or returning `{"decision":"block"}`
+- Added background monitor support for plugins via a top-level `monitors` manifest key that auto-arms at session start or on skill invoke
+- `/proactive` is now an alias for `/loop`
+- Improved stalled API stream handling: streams now abort after 5 minutes of no data and retry non-streaming instead of hanging indefinitely
+- Improved network error messages: connection errors now show a retry message immediately instead of a silent spinner
+- Improved file write display: long single-line writes (e.g. minified JSON) are now truncated in the UI instead of paginating across many screens
+- Improved `/doctor` layout with status icons; press `f` to have Claude fix reported issues
+- Improved `/config` labels and descriptions for clarity
+- Improved skill description handling: raised the listing cap from 250 to 1,536 characters and added a startup warning when descriptions are truncated
+- Improved `WebFetch` to strip `<style>` and `<script>` contents from fetched pages so CSS-heavy pages no longer exhaust the content budget before reaching actual text
+- Improved stale agent worktree cleanup to remove worktrees whose PR was squash-merged instead of keeping them indefinitely
+- Improved MCP large-output truncation prompt to give format-specific recipes (e.g. `jq` for JSON, computed Read chunk sizes for text)
+- Fixed images attached to queued messages (sent while Claude is working) being dropped
+- Fixed screen going blank when the prompt input wraps to a second line in long conversations
+- Fixed leading whitespace getting copied when selecting multi-line assistant responses in fullscreen mode
+- Fixed leading whitespace being trimmed from assistant messages, breaking ASCII art and indented diagrams
+- Fixed garbled bash output when commands print clickable file links (e.g. Python `rich`/`loguru` logging)
+- Fixed alt+enter not inserting a newline in terminals using ESC-prefix alt encoding, and Ctrl+J not inserting a newline (regression in 2.1.100)
+- Fixed duplicate "Creating worktree" text in EnterWorktree/ExitWorktree tool display
+- Fixed queued user prompts disappearing from focus mode
+- Fixed one-shot scheduled tasks re-firing repeatedly when the file watcher missed the post-fire cleanup
+- Fixed inbound channel notifications being silently dropped after the first message for Team/Enterprise users
+- Fixed marketplace plugins with `package.json` and lockfile not having dependencies installed automatically after install/update
+- Fixed marketplace auto-update leaving the official marketplace in a broken state when a plugin process holds files open during the update
+- Fixed "Resume this session with..." hint not printing on exit after `/resume`, `--worktree`, or `/branch`
+- Fixed feedback survey shortcut keys firing when typed at the end of a longer prompt
+- Fixed stdio MCP server emitting malformed (non-JSON) output hanging the session instead of failing fast with "Connection closed"
+- Fixed MCP tools missing on the first turn of headless/remote-trigger sessions when MCP servers connect asynchronously
+- Fixed `/model` picker on AWS Bedrock in non-US regions persisting invalid `us.*` model IDs to `settings.json` when inference profile discovery is still in-flight
+- Fixed 429 rate-limit errors showing a raw JSON dump instead of a clean message for API-key, Bedrock, and Vertex users
+- Fixed crash on resume when session contains malformed text blocks
+- Fixed `/help` dropping the tab bar, Shortcuts heading, and footer at short terminal heights
+- Fixed malformed keybinding entry values in `keybindings.json` being silently loaded instead of rejected with a clear error
+- Fixed `CLAUDE_CODE_DISABLE_NONESSENTIAL_TRAFFIC` in one project's settings permanently disabling usage metrics for all projects on the machine
+- Fixed washed-out 16-color palette when using Ghostty, Kitty, Alacritty, WezTerm, foot, rio, or Contour over SSH/mosh
+- Fixed Bash tool suggesting `acceptEdits` permission mode when exiting plan mode would downgrade from a higher permission level
+
+## 2.1.101
+
+- Added `/team-onboarding` command to generate a teammate ramp-up guide from your local Claude Code usage
+- Added OS CA certificate store trust by default, so enterprise TLS proxies work without extra setup (set `CLAUDE_CODE_CERT_STORE=bundled` to use only bundled CAs)
+- `/ultraplan` and other remote-session features now auto-create a default cloud environment instead of requiring web setup first
+- Improved brief mode to retry once when Claude responds with plain text instead of a structured message
+- Improved focus mode: Claude now writes more self-contained summaries since it knows you only see its final message
+- Improved tool-not-available errors to explain why and how to proceed when the model calls a tool that exists but isn't available in the current context
+- Improved rate-limit retry messages to show which limit was hit and when it resets instead of an opaque seconds countdown
+- Improved refusal error messages to include the API-provided explanation when available
+- Improved `claude -p --resume <name>` to accept session titles set via `/rename` or `--name`
+- Improved settings resilience: an unrecognized hook event name in `settings.json` no longer causes the entire file to be ignored
+- Improved plugin hooks from plugins force-enabled by managed settings to run when `allowManagedHooksOnly` is set
+- Improved `/plugin` and `claude plugin update` to show a warning when the marketplace could not be refreshed, instead of silently reporting a stale version
+- Improved plan mode to hide the "Refine with Ultraplan" option when the user's org or auth setup can't reach Claude Code on the web
+- Improved beta tracing to honor `OTEL_LOG_USER_PROMPTS`, `OTEL_LOG_TOOL_DETAILS`, and `OTEL_LOG_TOOL_CONTENT`; sensitive span attributes are no longer emitted unless opted in
+- Improved SDK `query()` to clean up subprocess and temp files when consumers `break` from `for await` or use `await using`
+- Fixed a command injection vulnerability in the POSIX `which` fallback used by LSP binary detection
+- Fixed a memory leak where long sessions retained dozens of historical copies of the message list in the virtual scroller
+- Fixed `--resume`/`--continue` losing conversation context on large sessions when the loader anchored on a dead-end branch instead of the live conversation
+- Fixed `--resume` chain recovery bridging into an unrelated subagent conversation when a subagent message landed near a main-chain write gap
+- Fixed a crash on `--resume` when a persisted Edit/Write tool result was missing its `file_path`
+- Fixed a hardcoded 5-minute request timeout that aborted slow backends (local LLMs, extended thinking, slow gateways) regardless of `API_TIMEOUT_MS`
+- Fixed `permissions.deny` rules not overriding a PreToolUse hook's `permissionDecision: "ask"` — previously the hook could downgrade a deny into a prompt
+- Fixed `--setting-sources` without `user` causing background cleanup to ignore `cleanupPeriodDays` and delete conversation history older than 30 days
+- Fixed Bedrock SigV4 authentication failing with 403 when `ANTHROPIC_AUTH_TOKEN`, `apiKeyHelper`, or `ANTHROPIC_CUSTOM_HEADERS` set an Authorization header
+- Fixed `claude -w <name>` failing with "already exists" after a previous session's worktree cleanup left a stale directory
+- Fixed subagents not inheriting MCP tools from dynamically-injected servers
+- Fixed sub-agents running in isolated worktrees being denied Read/Edit access to files inside their own worktree
+- Fixed sandboxed Bash commands failing with `mktemp: No such file or directory` after a fresh boot
+- Fixed `claude mcp serve` tool calls failing with "Tool execution failed" in MCP clients that validate `outputSchema`
+- Fixed `RemoteTrigger` tool's `run` action sending an empty body and being rejected by the server
+- Fixed several `/resume` picker issues: narrow default view hiding sessions from other projects, unreachable preview on Windows Terminal, incorrect cwd in worktrees, session-not-found errors not surfacing in stderr, terminal title not being set, and resume hint overlapping the prompt input
+- Fixed Grep tool ENOENT when the embedded ripgrep binary path becomes stale (VS Code extension auto-update, macOS App Translocation); now falls back to system `rg` and self-heals mid-session
+- Fixed `/btw` writing a copy of the entire conversation to disk on every use
+- Fixed `/context` Free space and Messages breakdown disagreeing with the header percentage
+- Fixed several plugin issues: slash commands resolving to the wrong plugin with duplicate `name:` frontmatter, `/plugin update` failing with `ENAMETOOLONG`, Discover showing already-installed plugins, directory-source plugins loading from a stale version cache, and skills not honoring `context: fork` and `agent` frontmatter fields
+- Fixed the `/mcp` menu offering OAuth-specific actions for MCP servers configured with `headersHelper`; Reconnect is now offered instead to re-invoke the helper script
+- Fixed `ctrl+]`, `ctrl+\`, and `ctrl+^` keybindings not firing in terminals that send raw C0 control bytes (Terminal.app, default iTerm2, xterm)
+- Fixed `/login` OAuth URL rendering with padding that prevented clean mouse selection
+- Fixed rendering issues: flicker in non-fullscreen mode when content above the visible area changed, terminal scrollback being wiped during long sessions in non-fullscreen mode, and mouse-scroll escape sequences occasionally leaking into the prompt as text
+- Fixed crash when `settings.json` env values are numbers instead of strings
+- Fixed in-app settings writes (e.g. `/add-dir --remember`, `/config`) not refreshing the in-memory snapshot, preventing removed directories from being revoked mid-session
+- Fixed custom keybindings (`~/.claude/keybindings.json`) not loading on Bedrock, Vertex, and other third-party providers
+- Fixed `claude --continue -p` not correctly continuing sessions created by `-p` or the SDK
+- Fixed several Remote Control issues: worktrees removed on session crash, connection failures not persisting in the transcript, spurious "Disconnected" indicator in brief mode for local sessions, and `/remote-control` failing over SSH when only `CLAUDE_CODE_ORGANIZATION_UUID` is set
+- Fixed `/insights` sometimes omitting the report file link from its response
+- [VSCode] Fixed the file attachment below the chat input not clearing when the last editor tab is closed
+
 ## 2.1.98
 
 - Added interactive Google Vertex AI setup wizard accessible from the login screen when selecting "3rd-party platform", guiding you through GCP authentication, project and region configuration, credential verification, and model pinning
